Added information:
My server uses iDRAC 6, and I have been told no update is available.

Hello,
I own a dedicated server hosted on hardware with an iDRAC (Dell)
middleware.
Fiddling with network configuration (attempting to configure a
bridge with libvirt to replace the current direct physical interface
configuration), I took the host machione down.
The technicians are unable to help me on the software-configuration
level, but they say there are conflict with the current version of
iDRAC and some Linux kernels.
Here is my (redacted) network configuration:
auto lo
iface lo inet loopback
#auto eth0
#iface eth0 inet dhcp
iface eth0 inet manual
auto br0
iface br0 inet dhcp
bridge_ports eth0
bridge_stp on
bridge_maxwait 0
bridge_fd 0
I crashed the machine down when addind the following snippet
(providing IPv6):
#iface br0 inet6 static
# address 2001:***
# netmask 64
# pre-up dhclient -cf /etc/dhcp/dhclient6.conf -pf
/run/dhclient6.eth0.pid -6 -P -v eth0
# pre-down dhclient -x -pf /run/dhclient6.eth0.pid
# bridge_ports eth0
# bridge_stp on
# bridge_maxwait 0
# bridge_fd 0
Note this part worked perfectly well when configured for eth0 as follow:
iface eth0 inet6 static
address 2001:***
netmask 64
pre-up dhclient -cf /etc/dhcp/dhclient6.conf -pf
/run/dhclient6.eth0.pid -6 -P -v eth0
What did I do wrong?

I do not really understand why you set up a bridge twice but I use a
rather similar setup for an Online.net hosted server with a dual stack
IPv4+IPv6.
As an example, my interfaces file is like this (Xen aware):
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto xenbr0
iface xenbr0 inet static
bridge_ports noregex eth0 regex vif.*
address
netmask 255.255.255.0
network

gateway
bridge_maxwait 5
bridge_stp off
bridge_fd 0
iface xenbr0 inet6 static
address 2001:bc8:
netmask 56
accept_ra 2
pre-up sleep 10 # see bug #783387
pre-up dhclient -cf /etc/dhcp/dhclient6.conf -pf
/run/dhclient6.xenbr0.pid -6 -P xenbr0
pre-down dhclient -x -pf /run/dhclient6.xenbr0.pid
Hope this helps.
